Dopterian interceptor

From Memory Alpha, the free Star Trek reference.

Dopterian interceptors are automated, hovering attack weapons employed by the Dopterians.

When selling weapons in 2373, Quark used a holographic Dopterian interceptor as a target to test a Breen CRM 114. (DS9: "Business as Usual")

This device's name appeared in an early draft of the script, and was not referred to but only seen in the aired episode.
